Nkhani - Ubwino Wotani wa Magalimoto Aatali Atali LiDAR?

Lembetsani ku Social Media Yathu Kuti Mutumize Posachedwa

Kuyerekeza Kosavuta pakati pa 905nm ndi 1.5μm LiDAR

Tiyeni tifewetse ndikumveketsa kufananitsa pakati pa 905nm ndi 1550/1535nm LiDAR machitidwe:

Mbali	905nm LiDAR	1550/1535nm LiDAR
Chitetezo kwa Maso	- Otetezeka koma okhala ndi malire pamagetsi kuti atetezeke.	- Otetezeka kwambiri, amalola kugwiritsa ntchito mphamvu zambiri.
Mtundu	- Ikhoza kukhala ndi malire ochepa chifukwa cha chitetezo.	- Utali wautali chifukwa ukhoza kugwiritsa ntchito mphamvu zambiri mosamala.
Kuchita mu Nyengo	- Zambiri zimakhudzidwa ndi kuwala kwa dzuwa ndi nyengo.	- Zimagwira bwino pakagwa nyengo ndipo sizikhudzidwa ndi kuwala kwa dzuwa.
Mtengo	- Zotsika mtengo, zigawo zake ndizofala kwambiri.	- Zokwera mtengo, zimagwiritsa ntchito zida zapadera.
Zabwino Zogwiritsidwa Ntchito	- Ntchito zotsika mtengo zokhala ndi zosowa zochepa.	- Kugwiritsa ntchito kwapamwamba kwambiri ngati kuyendetsa pawokha kumafunikira mtunda wautali komanso chitetezo.

Kuyerekeza pakati pa machitidwe a 1550/1535nm ndi 905nm LiDAR kumawunikira zabwino zingapo zogwiritsira ntchito ukadaulo wautali wa wavelength (1550/1535nm), makamaka pankhani yachitetezo, kusiyanasiyana, komanso magwiridwe antchito osiyanasiyana zachilengedwe. Ubwinowu umapangitsa makina a 1550/1535nm LiDAR kukhala oyenererana ndi mapulogalamu omwe amafunikira kulondola kwambiri komanso kudalirika, monga kuyendetsa galimoto. Nayi kuyang'ana mwatsatanetsatane pazabwino izi:

1. Kutetezedwa kwa Maso Kuwonjezeka

Ubwino wofunikira kwambiri wamakina a 1550/1535nm LiDAR ndi chitetezo chawo chowonjezereka chamaso a anthu. Mafunde ataliatali amagwera m'gulu lomwe limatengedwa bwino kwambiri ndi cornea ndi lens ya diso, zomwe zimalepheretsa kuwala kufika ku retina yomwe imamva bwino. Makhalidwewa amalola machitidwewa kuti azigwira ntchito pamagetsi apamwamba kwambiri pamene akukhala mkati mwa malire otetezedwa, kuwapanga kukhala abwino kwa mapulogalamu omwe amafunikira machitidwe apamwamba a LiDAR popanda kusokoneza chitetezo cha anthu.

DALL · E 2024-03-15 14.29.10 - Pangani chithunzi chowonetsa msewu kuchokera pamawonekedwe agalimoto ya LiDAR, ndikugogomezera kapangidwe kamsewu ndi mawonekedwe ake.

2. Nthawi yotalikirapo yozindikira

Chifukwa cha kuthekera kotulutsa mphamvu zapamwamba mosatekeseka, makina a 1550/1535nm LiDAR amatha kupeza nthawi yayitali yodziwikiratu. Izi ndizofunikira kwambiri pamagalimoto odziyimira pawokha, omwe amafunikira kuzindikira zinthu patali kuti apange zisankho panthawi yake. Utali wotalikirapo woperekedwa ndi mafundewa amatsimikizira kuyembekezera kwabwinoko ndi kuthekera kochitapo kanthu, kumathandizira chitetezo chonse komanso magwiridwe antchito amayendedwe oyenda pawokha.

Kuzindikira kwa Lidar kuyerekeza pakati pa 905nm ndi 1550nm

3. Kuchita Bwino Kwambiri Panyengo Yoipa

Makina a LiDAR omwe amagwira ntchito pa 1550/1535nm wavelengths amawonetsa magwiridwe antchito bwino pakagwa nyengo, monga chifunga, mvula, kapena fumbi. Mafunde aataliwa amatha kulowa mumlengalenga mogwira mtima kuposa mafunde afupiafupi, kukhalabe ndi magwiridwe antchito komanso kudalirika pamene kuwoneka kosauka. Kuthekera kumeneku ndi kofunikira pakuchita kosasinthasintha kwa machitidwe odziyimira pawokha, mosasamala kanthu za chilengedwe.

4. Kuchepetsa Kusokonezedwa ndi Kuwala kwa Dzuwa ndi Kuwala kwina

Ubwino wina wa 1550/1535nm LiDAR ndikuchepetsa kukhudzika kwake pakusokonezedwa ndi kuwala kozungulira, kuphatikiza kuwala kwa dzuwa. Mafunde enieni omwe amagwiritsidwa ntchito ndi makinawa sapezeka kawirikawiri m'magwero achilengedwe komanso opangira magetsi, zomwe zimachepetsa chiopsezo chosokoneza chomwe chingasokoneze kulondola kwa mapu a chilengedwe a LiDAR. Izi ndizofunika makamaka pazochitika zomwe kuzindikirika bwino ndi kupanga mapu ndikofunikira.

5. Kulowa kwa Zinthu

Ngakhale sichinthu chofunikira kwambiri pamapulogalamu onse, kutalika kwa mawonekedwe a 1550 / 1535nm LiDAR kumatha kupereka kuyanjana kosiyana pang'ono ndi zida zina, zomwe zimatha kupereka zabwino pamagwiritsidwe apadera pomwe kuwala kolowera kudzera m'zigawo kapena malo (mpaka kumlingo wina) kungakhale kopindulitsa. .

Ngakhale zabwino izi, kusankha pakati pa 1550/1535nm ndi 905nm LiDAR machitidwe kumaphatikizanso kuganizira za mtengo ndi zofunikira pakugwiritsa ntchito. Ngakhale makina a 1550 / 1535nm amapereka magwiridwe antchito apamwamba komanso chitetezo, nthawi zambiri amakhala okwera mtengo kwambiri chifukwa chazovuta komanso kutsika kwa magawo awo. Chifukwa chake, lingaliro logwiritsa ntchito ukadaulo wa 1550 / 1535nm LiDAR nthawi zambiri zimadalira zosowa zenizeni za pulogalamuyo, kuphatikiza mtundu wofunikira, malingaliro achitetezo, momwe chilengedwe, komanso zovuta za bajeti.
